'i IMPROVEMENT IMV OULTIVATOR.

To ALI. WHOM IT MAY OONOERN:

Be'it known that we, A; R. BLOO'D, A, HATIIAWAY, and V. R. BEACH, of Independence, in the county of Buchanan, and Stateof Iowa, have invented certain new and useful Improvements in Cultivators; and we do i hereby declare that the following is a full, clear, and exact description thereof, reference being had to theaccompanying drawings, and to the letters of :reference marked thereon, which form a part of this specification, in whicht Figure 1 represents Aa plan or top view of our machine, and

Figure 2 a side elevation ofthe same. l Y

The nature of this invention consists, first, in constructing the arms or Shanks of the cultivator-teeth 'with adjusting-holes; second, in the employment of levers, connected by a. cross-bar,.for.elevating the teeth; third, supplying the seed-slide .with a set-screw, for gauging the amountof seed to be sown; fourth, providing the cultivator with a pivoted frame directly beneathv the Acultivator-bars, to which frame the levers are attached; and, nally,.in the. employmentof a -rod-or bar, actingasa lever, for depressing the teeth in the ground, and attached to the piyotedj'rame, substantially in the manner hereinafter set forth.

To enable others skilled in the "art to make and employ our invention, we will now describe its construe,- tion and operation. i

In' the accompanying drawing'snlA represents the frame of the machine., upon which is secured the axle B. Secured to the axle, and resting upon` the front end ofthe frame, is the tongue 0. D D represent the wheels, which are placed on the axle B. vThe wheel D is provided, on itsinner side, with a pinion, tl, which is soldered or'otherwise secured thereto, and will be referred to further hereafter. E designates the seed-box, which is situated upon and secured-to the axle B, and. furnished, in its bottom, with diamond-shaped holes, for the exit of the seed. 6 represents a lever, having its fulcrum at z, and secured, at its lower end, to the diamond-shaped perforated seed-slide', shown in dotted lines in the drawings of fig. 1; c is the lid or cover of the seed-box, which is hinged or secured thereto by means of metal strips,ff, represented in dotted Alines in lig. 2. Secured andworking in the lower part of the seed-box E is the rod j, to theouter end of which is fastened a pinion,` c, which gears into the pinion d, formed on the inside of wheel D. 4F F represent the cultivator-bars, which are securedin place, at their front ends, to the under side of the front part of frame A by means of a metal rod, which passes through them, and is secured in the sides of said frame. Every other one ofthe ba'rs F F is made t0 project. outa suitable distance beyond the other, and provided'with `sl'ots,.in order to receivethe shanks of the cultivator-teeth G G. The upperends ofthe shanks of the cultvator-teeth G G are supplied with holes g, as shown iniig; 2, for the purpose of :adjusting ,the teeth to'any desireddepth in the ground; I designates a the pivoted Aframe I, is a bar or rod, L, which acts as a lever in de pressinnr or sinking the teeth in the ground, Awhenvoperated as will be stated hereafter. J' J designate two levers,'one of which is pivoted to each side of the seed-box, near its lower end, and fastened together, at their front ends, by means of a brace, which is held .in place by metal braces or loops passing around the endsof the levers. The lower or rear ends of the'lcvers are slotted, so as to receive one end of thestrips a a, the opposite end of said levers-being secured to thebar of' the pivoted frame I.' H designates a set-screw, which screws in a small metalplate, L, fastened to the bottom of the seed-box, and bent at right angles with it, so as to makeit parallel withithe seed-box, and thus allow the sere-w H to bc screwed againstorfrom the seed-slide, as the case may require. The object of this -arrangement is to gauge the quantity of seed to be sownby forcing or operating the screw against the slide, thus making smaller or lessening the size-oftheA holes in the slide. lis a catch, by means of which the levers J J are held down in place when themachine is not in motion, said catch engaging with another catch on the tongue ofthe machine.

Thevoperationof our machine is as follows: 'The driver, being `in position, will start the horses, drawing the machine over the ground to be furl-owed, in order to receive the grain at the same instant, end pressing the lovers J J upwards, lowering the teetlnend` cnusingthe bar Lto depress or sink the teeth into the'earth. .At the same time, pinion CZ, ou wheel D', will be operated, communicating motion to .pinion c, and causing rod 7' to be revolved, which will loosen the seed in the seedlbox, and allow tllem to escape through the holes in the bottom ,of the box, the seed-slide being gauged, according tothe size of holes required, by means of the'set-scrcw H, 'thus'furnisbinga simple and perfect means for cultivating the ground.

vWhat we claim a-s new, and desre'to Seeureby Letters Patentnis-g l. The levers J J, strips a a, bar L, and pivoted frame I, when all are atrnngod and operating substantially in the manner and for the purpose set forth.. l y 2. The set-screw H, seed-slide levers J J, strips a a, bar L H, pvoted frame I, all combined and arranged as and for the purposcrdescribed. Y

In testimony that we claim the'foregoing as our own, we aiix. ounsignatures in presence of two witnesses.
